Today, a Dell r730 XD on the company's shelves requires VMware ESXi 5.5 to be installed, and some problems have been encountered during the process, resulting in an estimated half-hour end of work that lasted nearly four hours.Issue 1: Server is 1U, hard disk full, no optical driveAnswer: More than treat the U disk, so did a U disk startIssue 2: Disk array not recognizedAnswer: Modify the disk mode to ATA in the BIOSIssue 3: "Buffer too small" hintA:

The author needs to face the environment for time synchronization has a higher requirement, and the virtualized environment time is more prone to problems, you can refer to the previous blog post Why is the synchronization on the domain controller very important? The author of the environment, after personal observation, if there is no time synchronization, virtual machine and standard time gap in just two hours unexpectedly on the deviation of nearly half an hour! According to VMware KB 100306

The allocation target can be either the IP address of the VMware ESXi or the MAC address, as an example of the MAC address of the ESXi network card in this example.(1) in i

We are familiar with the method of customizing ESXi installation image is basically esxi-customizer-v2.7.x to complete, today I give you a new method, this method in ESXI6.0 start more suitable, as for why we try to know more.The Preparation tool requires:ISO files for Vmware-powercli-6.3.0-3737840.exe and Esxi-customizer-ps-v2.4.ps1 and

Because the work requires installing an esxi5.x for the experiment, we bought a thinkstation which is cost-effective. I have considered it before I buy it. I either install the window system directly, install workstation 10, and Virtualize esxi; or install esxi 5.xon bare metal. I chose the second solution, but the problem arises...

After playing ESXi for a few days, the virtual network configuration can be easily summarized in some circles. At present, it cannot be said that it is very proficient, but it can be accumulated. Network deployment Diagram The following is a simple server network deployment diagram. Three networks are planned in the topology. One is the Internet: WAN, and the other is the office network: LAN (access in the office environment ), one is Private LAN (se

Microsoft's Hyper-V and VMware ESXi are architecturally different, but many virtualization administrators are unaware of these differences. And many administrators are also confused about how Hyper-V is running on the host operating system.A common misconception about Microsoft Hyper-V is that installing Hyper-V requires the use of the Windows operating system, and Hyper-V runs on top of the host operating system rather than directly on bare metal. It

VMware vSphere server virtualization Lab 1 ESXi 5.1 is a core component of vSphere, similar to Windows Hyper-vServer and Citrix XenServer, it is a system that can be installed and run independently on the supervisor. Therefore, unlike VMware Workstation, it no longer depends on the host operating system. After ESXi is installed, You can remotely control the connection through the vSphere Client, and then cr

Use Gpxelinux for the PXE automated installation of ESXi 5.x under Windows. Many of the tutorials on the web are using Linux as a PXE server, which is really a headache for kids who aren't familiar with Linux, like me. So I collected data and tried to build a PXE server under Windows and use it to batch install ESXi 5.x.The first self-summary is the process by which the server uses PXE boot. 1. After the

Managing multiple ESXi hosts through vCenter Server Through the introduction in the previous three chapters, we already have some knowledge about virtualization. However, it is all basic things that make no sense in practical use. Starting from this chapter, we will officially step into the core of virtualization technology. Over time, we will learn more and more deeply. Add multiple ESXi instancesHost join

The previous article has learned how to install the ESXi host, then we need to learn how to install the Windows virtual machine on the ESXi host, the ESXi host is based on the Linux kernel Ah! Do you want to write a command to create a Windows virtual machine, huh! Don't worry, VMware provides vsphere Client management tools and must be used to create virtual mac

First, you must note that (after testing) The general PC can install esxi 3.5. But not any PC. What are the conditions? You can refer to the following considerations. The installation process is simple. You just need to step by step. Test Machine Configuration: Asus p5pl2 motherboard, Pentium D 820 CPU, 1 GB memory, Sata hard drive, general ide optical drive, 3c905b Nic Note: 1. The machine memory must be at least 1 GB; otherwise, an error is retu

Because the memory is usually the most limited resource, esxi uses the memory overprovisioning configuration (memory overcommitment, that is, the memory of the configured virtual machine may exceed the physical memory (RAM) to manage the memory. During memory overuse configuration, esxi must use technology to reclaim memory from one or more VMS. These technologies are called transparent page sharing (TPS) a

Because the test needs every it cock silk will need one or two test server, but not enough for a machine to install a system ah, so it is necessary to assemble a high-performance testing machine to do virtualization, let's say a DIY ESXi virtualization server (of course, this does not consider server security issues)!First, the choice of hardwareCpu:xeon e3-1200 V3 Series * 1 pcs (BULK)Memory: Kingston DDR3 8G * 4HDD: Kingston 120GB + 250G SSDMotherbo
